Help text

The PCI device stub driver provides limited version of the PCI device backend driver without para-virtualized support for guests. If you select this to be a module, you will need to make sure no other driver has bound to the device(s) you want to make visible to other guests.

The "hide" parameter (only applicable if backend driver is compiled into the kernel) allows you to bind the PCI devices to this module from the default device drivers. The argument is the list of PCI BDFs: xen-pciback.hide=(03:00.0)(04:00.0)

If in doubt, say m.
